10Claims.

This invention relates to weather strip construction and-particularly to a composite weather strip adapted for use in window casingshaving sash frames slidably. mounted therein.

One object of the present invention is to provide a novel construction and arrangement in weather stripping whereby sticking or binding of the sash members or frames in their movement in the window casing is eliminated.

Another object of the invention is to provide a weather strip whereby rattling of the sash members in the window casing is prevented.

Another object of the invention is to provide a novel construction and arrangement wherein eilicient contact of the respective elements is maintained regardless of the expansion or contraction of the sash frames or the window casing.

Another object of the invention is to provide a weather strip of the character described which eliminates the necessity of parting strips on the window casing, and which is adapted for use with standard sash frames without the necessity of extra or additional grooving of the sash.

A further object of the invention is to provide a weather strip which is durable, economical, simple to install, and which will provide a maximum of protection against weather conditions to which the device may be subjected.

A still further object of the invention is to improve devices of the character described in sundry details hereinafter referred to and particularly pointed out in the appended claims.

One embodiment of the present invention is shown for illustrative purposes in the accompanying drawing, in which:

Fig. 1 is a plan sectional view through a portion of a window casing and stops mounted there- .on illustrating the application of my improved weather strip construction thereto before positioning the sash frames within the window casing;

Fig. 2 is a view similar to Fig. 1, illustrating the arrangement of the improved weather strip construction after the sash frames have been positioned within the casing;

Fig. 3 is afragmentary perspective view of a portion of my improved composite weather strip; and

Figs. 4 and 5 are fragmentary perspective views, respectively, of oppositely disposed angle strips adapted to cooperate with the structure illustrated in Fig. 3, and forming a part of the present invention.

As illustratedin the accompanying drawing, the present invention is shown in relation to a in a manner to be positioned under tension between the casing Band inner and outer sash frames H and I2, respectively, as illustrated in Fig. 2.

The intermediate member is shown, in the present instance, as comprisingan elongated substantially U-shaped projection 13 adjacent its central longitudinal portion to provide a hollow parting strip adapted to be positioned betweenadjacent end and side portions of the inner and outer sash frames I l and i1, respectively, as illustrated in Fig. 2, the member 9 being provided also with oppositely disposed wing portions I4 and I5 extending laterally from the respective opposite sides of the projection l3 and terminating slightly short of the inner and outer stops 1 and 8, respectively, in a manner to permit a degree of lateral movement of the member 9 in either direction with respect to the stops I and 8.

Mounted in the casing 6 adjacent the respective inner and outer stops I and 8 are a pair of oppositely disposed angle strips formed of resilient sheet-like material, and indicated, as a whole, and respectively, by the numerals l5 and H, the said strips comprising leg portions 18 adapted to be positioned between the respective inner and outer stops and an adjacent sash frame to provide a metallic wearing surface along which the sash frames may slide, the said angle stripsili and I1 being provided with a second--leg portion l9 extending at an angle to the leg portion [8 and adapted to be positioned adjacent .the casing 6 and between the inner face]! thereof and the edge portion of the wings I! and i5 formed on the intermediate member 8, as clearly illustrated in Figs. 1 and 2.

It will be noted by reference to Figs. 1 and 2 that, owing to the resilient character of the material of which the angle strips l6 and i! are formed, the angle of the respective leg portions l8 and I9 thereof will be increased from that shown in Fig. 1 to that shown in Fig. 2, when the sash frames II and 12 are positioned in the casing 6, thereby placing the angle strips under a tension as illustrated in Fig. 2.

As illustrated in the drawing, the respective wings l5 of the intermediate member 9 are provided adjacent their outer edges with curved portions 22 forming concave surfaces on the side thereof adjacent the casing 6, and the leg portions I9 of the respective angle strips l6 and I! are provided with transversely curved portions having a convex surface on the side thereof adjacent the wings l4 and I5 and adapted to be engaged by the curved portions 22 thereof in a manner to iie substantially parallel thereto when the intermediate member 9 and angle strips l6 and I! are in operative position with respeetto the casing 6 and sash frames II and 52, as illustrated in Fig. 2, thereby providing a most efficient structure to reduce infiltration to a minimum and provide a maximum degree of protection against weather and atmospheric conditions to which the device may be subjected.

It will noted by reference to Fig. 2 that the bearing or engaging portion of the respective sash frames l I and I 2 is adjacent the angle 23 formed by the respective sides of the projection l3 and the inner portion of the respective wings M and I 5, and that by reason of the resilient character of the material from which the member 9 is formed and the relative position of the sash frames and weather strip with respect to the casing, the sash frames II and [2 are free to yield in a sidewise as well as an inwardly and outwardly direction and yet retain eflicient weathertight contact of the respective elements to provide an eflicient weather strip construction. This feature is most desirable in view of the usual expansion and contraction of the sash frames due to weather conditions, in that the arrangement shown and described eliminates sticking or binding of the sash frames in the casing, and at the same time retains suflicient contact to reduce infiltration to a minimum and prevent rattling of the sash frames within the casing.

It will be observed from the foregoing description that in addition to the advantages above mentioned, the present invention eliminates the necessity of parting strips on the window casing, and that by reason of the hollow character of the projection l3 of the intermediate-member 91, the weather strip of the present structure permits lateral movement of the sash frames with respect to the casing, and the projection I 3 may be formed as to adapt the structure for use in connection with standard sash frames without the necessity of extra or additional grooving of the frames.

It will be observed also that the present invention provides a weather strip construction which is durable, economical, simple to install, and which will provide a maximum of protection against weather conditions to which the may be subjected.

Obviously, the present invention is not limited to the precise construction and arrangement shown and described as the same may be variously modified. Moreover, all the features of the invention need not be used conjointly as the same may be used to advantage in variously different combinations and subcombinations.
